There's an edge cause with gapless audio and pausing. Since, gapless audio works by sending an EOF immediately, it's possible to pause on the next file before audio actually finishes playing and thus the sound gets cut off. The fix is to simply just always do an ao_drain if the ao is about to set a pause on EOF and we still have audio playing. Fixes #8898.
